Submit one of these 9 more specific codes instead:

  • O66.0 Obstructed labor due to shoulder dystocia
  • O66.1 Obstructed labor due to locked twins
  • O66.2 Obstructed labor due to unusually large fetus
  • O66.3 Obstructed labor due to other abnormalities of fetus

  • O66.6 Obstructed labor due to other multiple fetuses
  • O66.8 Other specified obstructed labor
  • O66.9 Obstructed labor, unspecified

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
